Enhancement Request: User-supplied SSL certificates for remote management

Netgear always promoting their products have very high security and usually announce a lot of so called "Security Advisory" about their products, and also provide a firmware upgrade to fix the security issues. But currently, if you login to your Netgear router everytime, almost all of the internet browers saying it is insecure, with a big red label to telling you the connection has a risk for leaking your information. This issue already happened more than 4 years, is it Netgear discards their security standard and put their product with a risk forever?

As per Netgear response, you can choose to use a third party firmware to fixed the problem, but in another channel they say if you use a third party firmware it is very high risk as they cannot ensure the information safety.

As a large company or enterprises, I cannot choose such kind of insecure product, this is a very well known issue and easy to fix by adding a let's encrypt feature or upload a certificate manually. As a home user, there have many alternative product in the market already provided a solution for that. So, why we still choose Netgear?
